Union of the Comoros

The flag of Comoros is composed of four equal horizontal bands of yellow, white, red and blue, with a green isosceles triangle superimposed on the hoist side of the field. This triangle has its base on the hoist end, spans about two-fifth the width of the field and bears a fly-side facing white crescent and four five-pointed white stars arranged in a vertical line along the opening of the crescent.
